Question

A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of ethanolamine, dimethyl sulfoxide, glycerol, diethylamine, and pentane. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density ethanolamine 1.0gmL dimethyl sulfoxide 1.1gmL glycerol 1.3gmL diethylamine 0.71gmL pentane 0.63gmL Next, the chemist measures the volume of the unknown liquid as 1857.cm3 and the mass of the unknown liquid as 1.31kg. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. g/mL Given the data above, is it possible to identify th liquid? yes no If it is possible to identify the liquid, do so. ethanolamine dimethyl sulfoxide glycerol diethylamine pentane

Answer 1

Yes it is possible to identify the liquid with the help of measurements done.It was diethylamine.
